Blender 2.8 delete unused animations

Maybe is time add delete button at animations drop down menu.
I deleted all keyframes in action editor, i checked if not some keyframe from mesh, i uncheck buffer markt, restart project, and anyway empty animations was in Action editor, then restart couple times this Blender 2.81, and in the end animations was gone after three times restarted program. In 2.79 was not so many problems, sorry, but it’s true.
